I have just had the car serviced and thought I’d check that the engine cover had been refitted correctly and noticed the engine block and bell housing has what I think is corrosion (or oxidation?), it looks like a white powder stuck to the block.
Should I be concerned? Also is there anyway of removing this and stopping it reappearing?
The aluminium coloured top cover also has some marks.
I’ve owned the car from new and am not aware of any leaks under the bonnet.
All views appreciated. Thanks.
Engine block corrosion?
It certainly looks like some kind of oxidation reaction, if I am not mistaken the block is made of aluminium alloy.
Is the car garaged, or is there humidity where you keep the car?
Try a careful steam clean the block and after it drys spray a little wd 40 on the effected area.
Good luck.

Aluminum shouldn't rust.
Is it on any other part of the car ?

I have seen this on most cars I have owned and I have just brushed it off and gave components a regular coat of WD40. The white powder effect is just oxidation and it forms a skin. If you clean it off the process will just start again. I found that by spraying on WD40 on the exposed components slowed the process down.

I noticed this corrosion to the aluminium engine block and bell housing a while ago and some of the crevices in that area were also holding the white powder. I hosed it off but it returned over a relatively short period of time.
My car is exposed to the elements all year round as I don't have a garage.
I have a feeling that the corrosion could be caused by water and moisture entering through the bonnet vents?
I've got the ‘open mesh’ vents........do you also have the same or do you have the ‘shrouded’ vents? (first photo is the ‘open mesh’ vent).

Thanks all for the comments.
I do have the open mesh vents and the car lives outside as I also do not have a garage.
It seems that it is not that unusual, I’d prefer for it not to have that extent of corrosion / oxidation on it and am wondering if I will be able to clean it up and slow down it reappearing.

This amount of corrosion shouldn’t be happening and I think it will eventually cause big problems if left to its own devices.
To help prevent it getting any worse I’ve been considering replacing the ‘open mesh’ bonnet vents with the ‘shrouded’ type. My only concern is that they have a few very small holes in them which doesn’t do much for heat dissipation.
When my car engine is warm, I can put my hands over the ‘open mesh’ vents and really feel the heat that is being released from the engine bay.
I wonder if those cars which had the ‘shrouded’ vents from date of manufacture are showing any signs of corrosion (as per your photos). The comparison would be best made with cars that are also exposed to the elements all year round and are of a similar age (mine is 2016).....I’m not sure when the ‘shrouded’ vents were first introduced on the F-Type though?

Sounds like an option although it would be difficult to get to all the corroded areas. Also, it would need to be done on an annual basis or sooner.
Would it be safe to use on the F-type engine block etc?
Had a look on http://www.acf-50.co.uk/ and it says this......
“The unique abilities of ACF-50 remain effective for 12 months, gradually disappearing as it is chemically consumed.”
On Motorbikes.......“Use ACF-50 anywhere (except the brakes) including the engine and exhaust (will smoke on first start and burn off down pipes but still slows down corrosion process).”
I wonder if you’d see any smoke from the engine bay etc on starting up the F-Type after applying ACF-50?
